YCONNECTER. FOR ELEGTIC WIRES.

Application i1ed-March 171'922.' '.S'eral No. 544,426.

To all whom t may concern: I

Beit lknown that I, AGrUs'ivu/n M. BonnN, a citizen of the United States, residing at Chicago, in the county of Cook and lState of Illinois, have :invented certain new and use- `fullmprovements in Connecters for Electric Wires, of which the following is a specication.

The invention relates to connecters for electric wires and is more particularly di- Irectedato connecters for connecting a service wire to the terminal posts in a fuse box.

The primary object ofthe invention is to provide a connecter for temporarily connecting a service wire with the terminal gposts kof the insulating block in 'a fusebox forming a part of the` specification, and in which the preferred embodiment of the inat 37, 38 for adjfu'stably receiving therevention is depicted. A

In the drawings, Fig. 1 is a front elevation view of a fuse box with the door thereof thrown open showing an insulating block and the invention affixed to the fuse box.

Fig. 2 is a side elevation view similar to Fig. 1 with the side wall of the fuse box removed.

Fig. 3 is an elevation view of the service wire supporting arm.

Fig. 4 is an end view of the service wire supporting arm.

Fig. 5 is an enlarged detail view of the service wire supporting arm in contact with the binding posts, a portion of the supporting arm being broken away.

For a more comprehensive and detailed understanding of the invention reference may be had to the accompanying drawings in which like reference characters refer to like parts throughout the drawings. Reference character 10 indicates a fuse box having a door 11 hingedly related thereto as at 12. Within the fuse box 11 and secured to the rear. wall 13 thereof is insulating block 14 having contacting plates 15, 16, fuse plug 17 and terminal posts 18, 19, as is usual in suchidevices. VThe servicewiresupporting arm 20, which may be-made of any -insulating material, preferably wood, vhascontacting members 21, 22 extending beyond the inner end'thereof, which members 21, 22 ter! minate yin circular or ring-like ,portions y23,

24, which lie at substantially right angles to the service wire supporting arm, andare adapted yto encircle Vthe heads of binding screws 25, 26 and contact with termina-lxposts 18, 19 with their lower faces or bottoms.

VService Wire supporting arm 20 has groove 27 extending from the inner end of the farm to a point beyond the outer edge 28 of :fein rule .29, thereby forming ya passageway through whichservice wire 30 may be readily threaded. The strandsforming wire 30 may be readily threaded. The strands forming wire 30 are separated orsplit at the inner end of the service wire with one of the vstrands forming the service wire -secured toeach of the contacting members 21,

Vlby ybinding screwsV 31, 32, respectively.

The service wire supporting arm 2() issuplported by rod 33 of-bracket, designatedgenerally by reference character 34. The side members 35, 36 of the U-shaped portionof bracket 34 fare provided with openings as through rod 33. Setscrew .39 is provided in the head of the U-shaped portion of bracket 34 for securing rod 33 in adjusted vertical position. Adjustable clamp 40 secured to the upper extremity of rod 33 supports and provides means for adjusting supporting arm 20 horizontally. Side member 36 of U-shaped portion of bracket 34 is provided with set screw 41 for securing the connecter to the bottom wall of the fuse box 10. Service` wire 30 is provided with socket 42 of the usual construction. In making a connection with an electric system the bottom wall of fuse box 10 is inserted between member 35 of the U-shaped portion of bracket 34 and the inner end of set screw 41 with the ring-like portion 23, 24 of contacting members 21, 22 encircling screw heads 25, 26 with the bottom faces of the ringlike portions contacting with terminal posts 18, 19 and the connecter ysecured in position with relation to fuse box 10 by the operation of set screw 41 which co-operates with arm 35 to form a clamp for securing the connecter to the bottom wall of the fuse box.

rlhe invention is particularly adaptable 'for taking an electric current from fuse boxes such as are commonly found in apartment houses when it is desired to `use the current for a purpose other than that which the electric system contemplates, such for example, as the running of a washing machine or the like. The device is so constructed that the current will be ytaken from the main wires of the system and can therefore be subjected to heavy load without endangering thel system.

I claim: j l

l. A connecter for electric wires comprising a bracket, a wire supporting arm carried by the bracket, contacting members carried by the arm, and means for adjusting the contacting members with relation to the terminal posts of an insulating'plate within a fuse box.

2. A connecter for electric wires comprising a bracket, a wire supporting arm carried by the bracket, contacting members carried by the arm, means for adjusting the contacting members with relation to the terminal posts of an insulating plate within a fuse box, and means for securing the connecter to the fuse box.

3. A connecter for electric wires comprising an arm, contacting members carried by said arm, means for supporting said arm, means for adjusting the contacting members on said supportingmeans with relation to the terminal post ofan insulating' plate within a fuse box, and means for detachably clamping the connect-er to the wall of the fusebox. y

` 4. A connecter for electric wires comprising a bracket, contacting members carried by said bracket, means vfor adjusting tbe contacting members with relation to the terminals posts of an insulating plate within a fuse box, and means for adjustably securing the connecter to a fuse box.

.5. A connecter for electric wires comprising a bracket, al wire supporting arm carried by the bracket, contacting members carried by the arm, means `for adjusting the contacting members with relation to the terminal posts of an insulating plate within a fuse box, and means for adjustably securing the connecter to a fuse box.

6. A connecter for electric wires comprising a bracket, a wire supporting arm having a groove therein, a ferrule surrounding the arm and a portion of the groove, contacting members carried by the arm, means for securing the split ends of a service wire to the contacting members, and means for securing the connecter to the wall of a fuse box. 1

7. A connecter for electric wires comprising a bracket, a wire supporting arm carried by the bracket, contacting members carried by the arm, means fon securing the bracket to a fuse box, and means for adjusting the contacting members vertically and horizontally.

8. A connecter for electric wires comprising a bracket having a U-shaped portion, a supporting rod adjustably related to tbe U-shaped portion, a set screw extending between the side members of the U-shaped portion, and a wire supporting arm adjustably related to the supporting rod.

In testimony whereof I have signed my name to this speciiication, on this th day of March A. D. 1922.
